What is the safest speed to pass through the accident section?

20 kilometers/hour
30 kilometers/hour
50 kilometers/hour
It is safe to pass at any speed as long as safety is guaranteed.

New Zealand's traffic rules emphasize the necessity of reducing speed when passing an accident scene to ensure the safety of all road users. The correct speed is:

20 kilometers per hour.

This is because a lower speed allows drivers more time to react to unexpected situations and reduces the risk of secondary accidents caused by sudden braking or improper handling. Reducing speed to 20 kilometers per hour when passing an accident scene is also to ensure the safety of emergency service personnel (such as ambulance, police, and fire services) and to avoid exacerbating the consequences of the existing traffic accident.
